LOCK-LEVER CLIP FOR TEMPORARY BINDEBS.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed May 6, 1914. Serial No. 836,768.

To all whom it may concern Be it known that I, JOSEPH M. TOWNE, acitizen of the United States, residing at East Orange, Essex county,State of New Jersey, have invented certain new and useful Tmprovementsin Lock-Lever Clips for Temporary Binders; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to certain improvement-s in look lever clips fortemporary binders, but has reference more particularly to temporarybinders that are specially adapted to receive pamphlets, leaflets,catalogues, &c.

The object of my improvement is not only to provide a binder which maybe readily and independently attached to or disconnected from the usualposts or retaining members carried by a book back, but also to equip thebinder with locking means so that accidental detaching of the binderclips is impossible. Furthermore, each separate pamphlet isindependently connected to a binder post or other retaining membercarried by the book back, so that any pamphlet may be inserted within orwithdrawn from the binder without disturbing other pamphlets containedtherein.

In the drawings Figure 1 is an elevation of my improvement showing thelocking lever withdrawnFig. 2 a similar view showing the locking leverin its closed position with the retaining posts or members insection-Fig. 3 is a perspective view of a pamphlet in open condition,showing the slits made therethrough for the introduction of my improveddeviceFig. 4: is an elevation of such pamphlet showing the manner inwhich the clips extend from the back of the same, and also showinginsection a book back with retaining members in position to be engaged bysaid clipsFig. 5 an elevation of one form of the lock lever, and Fig. 6an elevation illustrating the form in which my improvement would beconstructed when used in connection with pamphlets that are wirestitched.

Similar numerals of reference denote like parts in the several figuresof the drawings.

1 is a sheet metal plate having formed integral therewith and extendingfrom one edge a pair of clips 2 provided with open gates 3, which latterpreferably extend 1n a direction substantially parallel with the lengthof said plate.

4 is a locking lever which is pivoted at one end at 5 to the side of theplate 1 about midway of the length of the latter, and extendlng from theinner edge of the free end of said lever is a tongue-like member 6 whichmay be provided wlthan open gate 7.

8 represents apamphlet, such as a catalogue, magazine or the like, andin applying my invention this pamphlet is opened, and slits 9 made fromthe inside through the back, these slits being spaced apart a distanceequal to that which separates the clips 2. The plate 1 is then placedwithin the pamphlet with the clips 2 extending through the slits9 andprojecting from the back of the pamphlet as'shown at Fig. 4E, and theseclips, which are in the nature of hooks, are then engaged around thebinder posts or other retaining members 10 carried by the book back 11.The lock lever is then operated to cause the tongue 6 to be driventhrough one of the slits 9 alongside the plate 1 so that its open gate 7will engage one of the posts 10, and in this connection it will beobserved that, when in this engaged position, the gates 3 and 7 willextend in directions substantially at right angles, that is to say, thetongue 6 will really be athwart the gate 3 at a point immediately beyondthe retaining member 10, so that the latter will be confined by saidtongue within the gate or hook portion of the clip 2. The outer wallportions of the gates 3 yield resiliently to admit the retainingmembers10, but this is not at all necessary since these clips 2 may be merelyhook-like devices, since the tongues 6 when in looking position willeffectually confine the retaining members 10 whether the clips 2 aremere hooks or are provided with open gates as shown. Likewise, thetongue 6 may be a mere hook-like member, or may be constructed as isshown at Fig. 5, since the friction between such tongue and the slot 9in the pamphlet will prevent accidental displacement of the lever 4L.Therefore, it is sufficient for the purposes of my invention, that thetongue 6 and its clip 2, when in locked position, should servecomplementarily to inclose a retaining member 10, although I prefer theconstruction shown at Fig. 1. v

The angular disposition of the gates 3 is immaterial although theirarrangement in a line substantially parallel to the length of the plate1 is the simplest embodiment of my invention in this respect.

At Fig. 5 I have shown the lever 4 with a plain tongue 12 extendingtherefrom, and, as I said before, this tongue will answer the purposesof my invention so long as it serves to confine the retaining member 10,and right here I will say that the latter may be in any of the Wellknown forms, either a post, ring,hook, prong, ac.

The form of my improvement illustrated at Fig. 1 would be used inconnection with a saddle stitched pamphlet, magazine, 81 0., but for a.side wire stitched pamphlet or magazine I would employ the form shown atFig. 6 where the width of the plate 1 is greater at its central portion,denoted by 13, which wider portion would be forced down against the foldof the pamphlet or magazine while the narrow portions at the end,designated. by the numeral 14:, would rest against the wire stitching.In all other respects, the construction shown at Fig. 6 is preciselylike that shown at Fig. 1.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. In a device of the character described,the combination of a binder plate having hook-like parts extending fromone edge which receive the retaining members of a temporary binder, anda locking lever carried by said plate and having a portion ex tendingfrom its inner edge and adapted in closed position to cooperate with oneof said projecting parts to complementarily incloseone of said retainingmembers.

2. In a device of the character described, the combination of a binderplate having clips with open gates which receive the retaining membersof a temporary binder, and a locking lever carried by said plate andadapted to be operated athwart the gate of one of said clips and beyonda sheet retain-'- ing member.

3. In a device of the character described, the combination of a binderplate having clips with open gates which receive the retaining membersof a temporary binder, and a locking lever carried by said plate andhaving a tongue and adaptedto be operated Copies of this patent maybeobtained for five cents each, by addressing the Commissioner of Patents;

to cause the latter to close the gate of one of the aforesaid clipsimmediately beyond the sheet retaining. member therein.

4:. In a device of the character described,

the combination of a binder plate having clips that eXtend from one ofits edgesand are provided with gates that open in a directionsubstantially parallel with the length of said plate and that receivethe retaining members of a temporary binder, and a looking lever pivotedto one side of said plate and having extending from its inner .edgeatongue which in the locked position of said lever closes one of saidgates, whereby the sheet retaining members are confined in the latter.

5. In a device of the character described,

the combination of a sheet metal binder plate having clips that extendfrom one of its edges and are provided with gates whose side walls areresilient and which receive the retaining members of a temporary binder,and a locking lever pivoted "at one end to said plate about midway ofthe length of the latterand'having extending from its inner edge nearthe other end a clip provided with a gate having resilient side wallsand adapted to receive one of said retaining members, the gates in theclips of said plate and lever opening indierections that aresubstantially at right angles.

6. In a device of the character described,

contained.

the combination of a binder plate having clips with open gates adaptedto be inserted through the back of a pamphlet from the Washington, D. C.
